To @ZZ whom it may concern:

Be it known that I, JOHN W. RAPP, a citizen of the United States, residing in the borough of Manhattan, city, o0^l1nty,and State of New York, have invented certain new and useful Improvements in Floor Construction, of which the following is a specification.

My invention relates toa floor construction.

I will describe a floor construction embodying myinvention and then point out the novel features thereof in the claims. -v

In the accompanying` drawings, Figure lis a perspective view, partly in section, of a floor construction embodying myinvention. Fig. 2 is a view similar to Fig. 1, but showing a modification. portion of an expanded metal'lath used in the iioor construction. Fig. 4 is a sectional view of the same. Fig. 5 is a view similar to Fig. 3, but showing a perforated metal lath. Fig. 6 is a sectional view of Fig. 5. Fig. 7 is a side elevationof a spacing-strip used'in the floor construction. Fig. 7.

Fig.V 8 is a bottom'view of Similar letters of reference designate corre-4 sponding parts in all of the gures.

A A represent I-beams, which may be supported or suspended in any desired manner and between which a portion of the door construction is supported. There may be any number of I-beams.

B represents the supporting-lath, the ends of which rest on the anges 0J of the,I-beams. The su pporting-lath is in sections. tion is provided with one or more loop portions b, which extend from one edge tothe opposite edge, and openings b intermediate the loop portions. In the drawings I have shown each section of lath as having three loopsone at each edge and one in the middle. It will be understood that any number of loops may be used. The loop portions are for the purpose of giving strength and rigidity to each section ot' lath, thereby enabling each section to withstand a greater load than it used without the loops. The openings between the loops may be formed by punching the metal, as shown in Figs. 5 and 6, or by slitting the metal and then stretching or expanding it to Fig. 3 is a detaiLtOp view of a [Each sec-V produce the appearance shown in Figs. 3 and' t. The expanded metal is preferable, for the reason that the edges of the slits turn upward and downward when the metal is being expanded which materially adds to the strength of the lath. It will be understood that the loops are without openings. In forming the floor construction theend loops on the adjashown in Figs. 7 and 8. In this case the strip is provided with loop portions c, and the metal c intermediate the loop portions is turned up' ward for the purpose o stitfening the spacing-strip. v

In'Fig. l the lath-sections are shown as being arched. The under side of the lath-sections-may be finished, and thus produce/an arched ceiling. If a fiat ceiling is desired with the arch, perforated lath Eis suspended between the I-beams A A. The lath E is held 'in place on the ilanges a by the ends of the lath-sections B. In Fig. 2 the lath-sections are shown as being flat.

What I claim asmy invention isy 1. In a floor construction, the combination of supporting-beams, a Hoor-filling between the beams, a support for said filling, said support being made up of sections each of which has formed in it a plurality of loop portions, and spacing-strips for said loop portions.

2. A spacing-bar for use in door `construc-` tions, made from a strip of metal and consisting of a number of loops and intermediate connecting portions which are turned upward.

3. In a ilooreonstructiomthe combination of Vsupporting-beanns, a'flo'or-filling between the beams, and a support for said filling, said support consisting of sections of expanded metal, each of which is provided with a plurality of loop portions.

4. In a floor construction, the combination of supporting-beams, a fioor-filiingand metallic sections intermediate the beams for supporting said floor-filling, said sections being 5 each provided with loop portions, and openings intermediate the loop portions, and spae- ,ing-strps for bracing the loop portions.

ln testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
